E-cigarettes and 'vaping' have not entered the social sphere without its fair share of controversy.

Well a new study may have just given the technology a strong public relations boost after researchers found that indoor vaping is 'unlikely' to pose a risk to the air quality of a room.

The research was a collaboration between Kaunas University of Technology in Lithuania, EMPA Swiss Federal Laboratories for Materials Science and Technology, ETH Zurich the Swiss Federal Institute of Technology and Fontem Ventures.

It's the first time a study has taken a detailed look at the chemical particles which are exhaled from e-cigarettes.

During the study the team looked at a broad range of closed-system e-cigarettes which are currently in use by the public and found that the liquid vapour evaporated in seconds with no affect to the background air quality.

To be sure the team also tried it in a room with no ventilation and found startlingly similar results.

Now it is important to note that this study was in fact carried out by Fontem Ventures, a company which happens to own two major e-cigarette brands.

That said, the research was carried out by independent educational institutions so while you can fault the reasons for the study being carried out, it's unlikely you'll be able to fault the results.

Despite the supposed benefits of using e-cigarettes over conventional tobacco-based cigarettes there has been considerable push back by the government to their social acceptance.

Wales in particular has taken a very strong stance on 'vaping', potentially banning its use from public areas.
